I use this script to print out the textual content of a fargo.io subtree to the JavaScript Console, numbering each subitem. Example output: 1. A 1.1 A1 1.2 A2 2. B 3. C See http://outliner.smallpicture.com/fargoVerbs.js for more background.

(function(){

    var t = Array();
    t.push(0);
    op.visitSubs ( 
            function (headline, levelnum) { 
                t[t.length-1] += 1;
                console.log(t.join(".") + ". " + headline.getLineText ());
            },
            function (levelnum) {
                t.push(0);
            },
            function (levelnum) { 
                t.pop();
            }
        );

})();
